ARTHUR J. FILKINS, 0F RIVERSIDE, ILLINOIS, ASSIGNOR TO PAUL DICKINSON INCORPORATED, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SMOKE-JACK.

Application filed January 14, 1916.

To all whom it may concern.

Be it known that I, ARTHUR J. FILKINS, a citlzen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Smoke-Jacks, of which the following is a specification.

This invention relates to smoke jacks or conduits for conveying the smoke from a locomotive when placed in position in a roundhouse away from the interior of the roundhouse to the outer atmosphere.

The object of the invention, is to provide a smoke jack of the character described, which shall be of improved construction and which shall be more convenient and effective in operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings, described in the following specification, and it is more particularly pointed out in the appended claims.

In the drawings;Figure 1, is a fragmentary sectional view through a portion of a roundhouse showing the smoke jack comprised in the present invention in side elevation. Fig. 2, is a detailed sectional view of a slide gate or valve used in connection with the present invention. Fig. 3, is a fragmentary sectional view of a portion of a roundhouse taken at right angles to Fig. 1, andv showing the smoke jack in elevation as viewed fro-m the right in Fig. 1. Fig. 4, is a fragmentary detail of a portion of the support for the counterbalance used in connection with the invention.

In modern roundhouse construction, it is now the usual practice to provide a chimney or stack located conveniently near the house proper, but, on a foundation independent of that of the building. smoke duct is positioned in the upper portion of the building, which is connected with the stack, and separate conduits or smoke jacks are provided for each stall or position for the locomotives in the house and these jacks are all arranged to discharge into the main duct and to be connected with the smoke stacks of the locomotives when they are in position in the house.

In the drawings, the numeral 1, designates the main smoke duct supported by timbers 2, near the upper portion of the Specification of Letters Patent.

house. The duct 1, is provided with a series of openings 3, one for each separate conduit or jack discharging into the duct, and each of these openings is provided with a slide gate or valve A, mounted to slide in guides 5, for opening and closing the communicating passage between the jack and the main smoke duct. The valve 4:, may be operated by any suitable means, a cable 6 being shown in the drawing for this purpose. A pipe section 7, is secured rigidly to the frame of the opening 3, and extends laterally therefrom in practice a distance between two and one-half and three feet. The pipe itself, is made approximately two feet in diameter. Arranged to telescope with the section 7, is a second pipe section 8, carried by hangers 9, suspended from a traveling roller 10. The roller 10, is mounted for movement on a trackway 11, supported by one of the timbers 12, of the roundhouse building. A second roller 13 connected with the roller 10, by means of links 14, is also mounted for movement on the track 11. The pipe section 8, is provided at its end with a downwardly turned elbow 15, which elbow is connected at its lower portion by means of a ball socket oint 16 with apivoted depending pipe section 17, the two parts being connected by pivots 18.

rigidly secured to the casing of the bell joint 16, and extending laterally therefrom, is a bracket arm19, connected by a link 20 with the pulley 13. The outer end of the bracket arm 19, is connected at 21, with a depending pivotal link 22, which is provided with counterbalance arms 23, pivotally mounted at 2d, at the lower end of the link. The pivot 2% forms a pivotal support or fulcrum member for the counterbalance arms. As shown in Fig. 3, the link 22, has a pair of laterally extending forks 25, and a pair of counterbalance arms 23, one on each side of the pipe section, are provided. Each of the arms 23, is provided with a forwardly extending segment 26, having an arcuate grooved periphery 27, for receiving a chain 28, attached at its end to the upper portion of the segment, as shown at 29, in Fig. 1. Suspended by the chains 28, is a pipe section 29, having tele' scoping connection with the section 17, and provided at its lower end with a spheri cally-shaped casting 30, to which are secured bales 31, carried at the ends of the chains 28. Suspended from the casting 30, by means of pivots 32, is a disk-shaped member 33, provided with a flat open bottom 3%.

As shown best in Fig. 1 the pipe section 17 is connected with the lower end of the link 22 by means of a link 35 having one end pivotally secured to the fulcrum rod 24 and the other end pivotally secured at 36 to the pipe section. By this arrangement, the fulcrum member 2a, of the counterbalance arms 23, is always maintained at a fixed distance from its pivotal connection with the pipe section 17. It will be apparent that the entire pivotally suspended portion of the smoke jack may be swung about its pivot 18 in either direction, indicated in broken lines, in Fig. 1, and that the ful crum 2 1 and the coimterbalance arm carried thereby, will be swung in unison with the depending pipe section. Weights 37, are carried at the ends of the arms 23 and are of the proper size to accurately counterbalance the telescoping section 29 of the depending pipe section, together with the parts carried thereby. By this arrangement, the telescoping section 29, may be raised or lowered relative to the section 17, and will be retained in whatever position it is moved into, the friction on the pivotal support 24, being sufficient to prevent accidental displacement. The adjustment of the section 29, is effected by a depending rope or cord 38, having one end attached to the arm 23, and a laterally extending rod on the other end similarly secured to the periphery 27, of the counterbalance segmen 26. The entire structure supportedby the rollers 10 and 13, is adjustable back and forth, toward and away from the main smoke duct 1, the adjustment being accomplished by means of a cable 39, which passes over a fixed pulley 40, secured to the timber 1'2, and which has its ends carried over guide pulleys 41, to a Windlass 12, located at a point convenient for operation. The lower run of the upper portion of the cable 39, is secured to an upwardly projecting lug 39, fastened to the movable section 8 of the horizontal extending portion of the smoke conduit, so that any movement of the cable 39, will cause this section to be telescoped in and out of the fixed section 7. The windss 42, is driven by a hand crank 13, which may be turned in either direction to shift the smoke jack toward or away from the main smoke duct 1. i

The operation of the device is as follows: The telescoping sections 29, of the various jacks in the roundhouse will ordinarily be left raised to a position somewhat above the level of the upper end of a locomotive smoke stack, indicated in broken lines, at 45. When an engine is run into the roundhouse, it Will be stopped with its stack approximately beneath the lower end of the jack. It is, of course, quite diflicult to stop the engine exactly beneath a fixed ack, and for this reason, the applicant has provided the means for adjusting his jack longitudinally of the direction of movement of the engine in entering the roundhouse. After the engine has come to a standstill, the hand crank 13, will be rotated in the proper direction to bring the swinging connecting member 33, directly over the upper end of the engine smoke stack, and the cord 38 will then be operated to lower the connection 33 and the telescoping section 29, until the connection rests in the upper end of the engine stack. The slide valve a, will in the meantime be opened to connect the jack with the main smoke duct and the escaping products of combustion from the engine will be carried upwardly through the jack into the smoke duct and thence to the chimney with which the smoke duct is connected. lVhen it is desired to remove the engine from the round house, the lower end of the smoke jack may be raised from the top of the engine stack and the engine driven from the house. It may sometimes happen, however, that the attendants will forget or neglect to raise the jack before the engine is started. In this case, with the old form of jacks, it has frequently happened that the jack itself is either bent or broken. lVith the present form, however, this is impossible, for the reason that if the engine is moved while the lower end of the jack is still in contact with the engine stack, the jack will merely be swung slightly in the direction of movement of the engine, as indicated in broken lines, in Fig. 1, until it reaches a position where it clears the upper end of the stack and the engine will continue to move outwardly without doing any damage. .Of course, it willbe understood that the telescoping adjustment of the members 7 and 8 of the jack could be dispensed with and the depending pivotal portion be swung about its pivot 18, to bring it into position over the top of the locomotive stack. It has been found in practice, however, to be desirable to provide the jack with both adjustments. When a particular ack is not in use, the valve is 'left closed to prevent any inrush of air through an idle jack, due to the draft in the main stack or chimney. When a cold engine is being fired, it is of very material assistance to be able to connect the stack of the engine with the draft in the main chimney through the smoke duct 1 and the smoke jack, thus creating a forced draft in the engine to assist in starting fires.

All of the parts of the jack, together with the main smoke duct 1, are preferably made of cast iron, since this material resists the action of the corrosive elements in the products of combustion from the engine furnace much more effectively, than other metals, such as wrought iron or steel.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is 1.
